| 摘 要： | 基于米氏散射(Mie scattering)理论,建立填充分散粒子群的聚合物对光散射传导的Monte Carlo数学模型.在此基础上,编写了一套仿真模拟程序.通过模拟单个光子在聚合物中的多重散射运动过程,把问题扩展到以激光束或线状光为入射源,得到在聚合物板块内的光传导情况,并且在计算机上图像化地重现整个物理过程,对输出光强的分布情况进行模拟统计分析.模拟结果表明,利用体散射机制,可以将点光源和线光源转换为平面光输出,输出光的状态可以通过对比计算结果实施有效控制.

| Abstract: | A mathematical model for multiple scattering of light conducted in polymers is presented.Based on the Mie scattering theory,Monte Carlo method is employed and a program is developed.By simulating scattering of a photon,we simulate problem with light source as laser or CCFL.Distribution of light out of source in polymers is obtained by statistic calculation.The results show that a plane light in polymer can be obtained with body scattering principle and intensity distribution of light escaping from polymer can be well controlled. |
